Thus swung the Pendulum

So, the Ninja called me tonight. I missed the call (making me look like a busy busy girl). But he left a message. Which was even more shocking; since he never leaves message (that would be far too responsible). The message basically asked what I was doing on Friday. And therein lies the question. Why is he calling asking what I'm doing on Friday? And since the only way the thought would cross his mind to ask me is if he broke up with his g/f or if the relationship is on the rocks....how long ago did that relationship start to spiral downwards? And, most importantly, do I care?
